STORM AND SCREEN WINDOW.

Specification of Letters Patent.

Application-filed January 28, 1910. Serial No. 540,35.

To all whom it may concern:

Be it known that I, BENJAMIN F. AUF onnnnmn, a citizen of the UnitedStates, residing at Davenport, in the county of Scott and State of Iowa,have invented certain new and useful Improvements in Storm and Screen\Vindows, of which the following is a specification.

This invention relates to improved window construction, and has for itsobject to provide a storm window which will be interchangeable with afly screen, so that either seasons.

An important object .of the invention is to provide such a windowconstruction of simple character adapting it to bemade at a low cost,and installed on windows of the usual type already built.

Another important object is to provide such a device, the removableelements of which may be manipulated from the interior of a buildingwithout the removal of the permanent window sash.

Other objects and advantages will be apparent from the followingdescription, and it will be understood that changes in the specificstructure shown and described may be made within the scope of the claimwithout departing from the spirit of the invention.

In the drawings: Figure 1 is an outside elevation of a window equippedwith my device, Fig. 2 is a similar interior elevation of the windowshowing one of the permanent sashes in open position, Fig. 3isahorizontal section through such a window, Fig.

4 is a vertical section therethrough, Fig. 5 is a detail section of ameans for-securing the storm sash in place, Fig. 6 is a modification andFig. 7 is a horizontal section of the outer frame.

Referring to the drawings, there is shown a window frame 10 of the usualconstruction in which are mounted the vertically recipro by its lowerend maybe swung outwardly at times if desired, for ventilation, as willbe subsequently described. Suitable fastening means gmay be employedupon the lower portion of the frame 13 to retain it securely in closedposition.

The inner sides of the rabbet 16 on the vertical portion of the frame 13are beveled outwardly, and corresponding horizontal portions of therabbet are similarly extended to a spaced distance from the inner faceof the frame 13, as shown at 19. At the upper sides of the openings 15an overhang 20 is provided inclined sllghtly downward, as shown in Fig.4. A second rabbet 21 is formed at the lower side of the openings 15,inwardly of the inclined portion 19f, in which there is secured thespring 22, which comprises a strip of resilient sheet metal havingavertical portion 23 secured against the inner sides of the rabbet 20,from which extends upwardly an inclined portion 24 corresponding to theoverhang 20 at the upper edge of the opening 15. From this upwardlyinclined portion the spring is inclined downwardly again for a shortdistance, after which it is turned inwardly and recurved as at 25, itslower end resting upon the lower side of the rabbet 21 and bearingresiliently thereagainst for support of the upper portion of the spring.This lower portion may be. secured to the lower end of the rabbet orleft slidably disposed thereon as shown in the modificationillustratedin Fig. 6:

Set snugly in the openings 15, there are storm sashes 30 comprisingrectangular frames of suitable material having rabbeted openings thereinprovided with glass secured in any suitable manner. The edges of thesash are all beveled inwardly toward their outer faces, as shown at 31,and on their upper and'lower edges are beveled inwardly toward theirinner faces as shown at 32, the upper inwardly beveled portions restingsnugly against the overhang 20 and the -lower inwardly beveled portionarranged to be engaged snugly by the inclined portion 24 of the spring22, which forces the sash inward, and holds it snugly in the frame 13.

In use, two sets of sashes are provided,

Patented July 25, 1911.

one having glass in as illustrated in the already described figures, andthe other havin suitable screens therein, as shown in Fig. 7 the firstbeing intended for use in winter, and the second to be applied insumbeing so disposed as to fold outwardly,

allowing the lower end of the frame to be swung outwardly as beforementioned. The upper storm sash 30 is inserted by lowering theupperpermanent sash of the window,

which leaves the upper opening 15 fully exposed, the sash-a30 being of asize small enough to pass through the space left by the lower sash. Theupper edge of the sash 30' is then presented beneath the overhang E20,and the lower edge swung outwardly, the sash being meanwhile pressedfirmly against the upper edge of the opening 15. The lower beveled edge31 of the sash will thus engage upon the outer inclined portion of thespring: 22, forcing it downwardly, and allowing the sash to be snappedinto place in the frame 13, after which the spring 24 will be pressedupwardly by the resiliency of the portion 25, bearing upward and inwardagainst the sash 30 and holding it snugly in place. The removal of thesash is accomplished by simply drawing inward upon the sash, the spring22 yielding to a certain amount of force properly applied.

In order to facilitate this finger notches 34 may be provided, or anyother suitable means for drawing the sash inward. The application of thelower sash 30 is accom plished in a similar manner.

When in winter a short spell of warm weather is experienced, the lowerend of the frame may be swung outwardlyand propped by any suitablemeans, or if an extended period of Warm weather should occur the sashes30 may be removed for as long a period as may be desired. In summer thesashes 30 are simply removed as described, and the screen sashessubstituted.

What is claimed is:

A stormsash having openings there through and detachable sectionsadapted to be secured therein, a fastening device comprising a strip ofmetal having a vertical attaching flange adapted to be secured to saidsash, an angular wall, a forward compound curved wall having its loweredge free, said removable sections having grooves for engagement withsaid angular wall to hold said sections in position. i

In testimony whereof I affix my signature, in presence of two witnesses.
